shutdown now && poweroff was only possible as root, at least that's what I'm told when I enter it in a terminal as user.
In another thread bicol_willem gave me a hint that he places a desktop icon for shutdown, command: "halt"
As my parents already had the issue of the shutdown widget not working three times, I thought this might work. So I created a menu icon, but entered the command
shutdown now && poweroff.
When I click the entry, a window pops up asking me for the root password. After entering the computer shuts down.
If I click "abort" the system shuts down the same way without asking for the password.
I wasn't able to find out if it really performs the same procedure in both cases.
Is there anyone more knowlagable than me who could explain what is going on? Shouldn't "Abort" bring me back to the desktop?
